Application filed January 28, 1924.

This invention relates to shingles and one of the objects is to produce a shingle of pre pared roofing material of such a design that a roof constructed from such shingles will, when Viewed edgewise, show up the successive laps of the'shingles in three-ply form, thus presenting a layer of roofing of heavier, more substantial, and more attractive appearance than the single-ply prepared roofing now generally used and as usually laid.

Another object is to produce a shingle so constructed that the exposed corners of each shingle can be interlocked with the shingle below to guard against the tearing or ripping loose of the shingles by the force of high winds.

With the objects named in view, the invention consists in certain novel and useful features of construction and organization or" parts as hereinafter described and claimed; and in order that it may be fully understood, rei erence is to be had to the accompanying drawing in which 1- Figure 1 is plan view of a shingle embodying the invention.

Figure 2 is a plan view of a modified fOllH of the invention.

Figure 3 is an edge view to illustrate the appearance of the completed roof.

Figure 4 is a top plan view of a section of root.

Figure 5 is an enlarged plan view to illustrate the interlocking of the exposed corners of the shingles.

Figure 6 is a section on the line VIVT of Figure 3.

In the said drawing, where like reference characters identify corresponding parts in all of the figures, 1 represents the rectangular body portion of a shingle embodying the invention. Formed integrally with and projecting from one edge of the body portion are a pair of extensions or tab portions 2 and 3, which are of equal width, but the tab portion 3 is twice as long as the tab portion 2. In this connection it is desirable to point out that the tab portions 2 and 3 are formed equal distances from the opposite ends of the body 1 of the shingle to form a pair of shoulders 8 and 9, whose combined widths are equal to the width of either of the tab portions.

Serial No. 689,070.

The extensions or tab portions 2 are longitudinally slotted at their lower edges as at t to form a pair of ears 5. The lower corners of the tab portions 3 are provided with transverse and preferably curved slits 6 to form a pair of ears 7. The slits 6 of each shingleare designed to be engaged and interlocked with the slots 4 of the tab portion 2 of the next underlying shingle 2, with the corresponding ears 7 underlying the ears 5 of said tab portion, as illustrated in Fig ures 3 to 5.

The operation of laying the shingles is as tollowsz-Reterring to Figures 4 and 5, it will be noted that the shingles are laid in horizontal rows, commencing from the bottom edge of the roof, after a suitable plain edge strip (not shown) has first been applied. The shingle A in the first row is secured in position, and the shingle B comprising the next above horizontal row is laid with its extension or tab portion l3 over lying the tab portion A and having its ears B engaged through the slots A, thus exposing the ears A above the ears B as illustrated. The shoulder portion A underlies he tab portion B for one-halt of the width of the latter, as shown in dotted lines. The shingles of each successive horizontal row interlock as described, and in Figure 4, the interlocking of a shingle C in the third horizontal row with the shingle B is illustrated. The ears B are exposed through the slits C and the slots C are in position for engagement with the ears 7 of a shingle in the nextsucceeding horizontal row. The shoulder B underlies one-half the width of extension or tab portion C and being abutted by the shoulder X of the shingle X in the same horizontal row.

l/Vith the method described of laying a roof, a three-ply or triple thickness root is produced in the lapped portions thereof which are presente-dto edgewise view, the exposed corners of the extensions or tab portions of each shingle being interlocked with the shingle below to stifien the shingle and counteract the tendency of a wind to tear or rip the shingle lose from its fastenings.

Considering the successive layers of the shingles of the middle portion of the shingle assembly shown in Figure 3, and starting abutting ends of the shingles E and F, the

respective edges 8 and 9 of which are let exposed. Overlying these ends of the shingles E and F is the tab portion 2 of the shingle G which is interlocked in the manner above described with the overlying tab portion 3 of the shingle H. Uponthis portion 3 of the shingle H are laid the abutting ends 8 and 9 of the shingles I and J, leaving the edges thereof exposed. Upon these end portions of the shingles I and Ll is placed the tab portion 2 of the shingle K, which in :turn is interlocked in underlying relation to the tab portion 3 of the shingle L. In the same superposed relation over this portion 3 of the shingle L are arranged the abutting ends of the shingles M and N, the tab portion 2 of the shingle O and tab portion 3 of the shingle P. Each of the other .portions of the roofing, when completely laid, are built up and assembled with all the exposed edges in three-ply formation, and it will be noted that in each instance these three -ply unit portions comprise the parts 8-9, 2 and'3 of the successive shingles, and these several unit portions occur at regular intervals the same distance apart, equalt-o the length of the tab extension 2. This produces not'only the desired etfect of thickness and inultipledayer structure, but also an arrangement of ornamental appearance, due to the continuous stepped design obliquely in either direction from the bottom to the peak of the roof.

It will be apparent that the shingles may be nailed in position or. secured in any other suitable manner, as common in; the art. Figure 2 of the drawing indicates shlngle corresponding in all particulars to the shingle shown in Figure 1, except that it is not provided'with the slots l and'slits 6 produced in the tab corners of the extensions.

This-type of shingle is secured in position in accordance with the methods above described, except that the corners are not interlocked, although it desirable a locking clip or other fastening device of any desired character may be provided. It is also apparent that the improved type ozt'construction is adapted not only for use as individual units, but may also be embodied in the. continuous strip form of rooting.

From the above description. it willbe ap parent that we have produced ashingle of the character described which'possesses all o'fthe features of advantage set forth as desirable, and while we have described the preferred embodiment of the same, we reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

Vi e claim 1. A shingle comprising a body portion formed along one of its edges with a plurality of downwardly extending contiguous tab portions of equal Width but unequal'length,

those tab portions adjacent to the ends of the body portion being spaced equal distances from saidends of the body portion.

portions adjacent to the ends olfthe body portion being spaced from said ends of the body portion. i

3. A shingle comprising a body portion formed along one of its edg'eswith aplurality of downwardly extending tab portions of unequal length, those tab portions adjacent to the ends of the body portion being spaced from said ends of the body portion, one of said tab portions being provided with means for interlocking with the superimposed tab portion of a second shingle.

4-. A. shingle comprising a body portion formed along one of its longitudinal edges with a pair of downwardly extending contiguous tab portions of equal width but imequal length and spaced'troin the 'ends' ot' the body portion, the combineddistances of portions of successive shingles superposed by the shorter and longer tab portions re spectively 0t superposed shingles.

6. A roof structure comprising shingles having body portions and tab portions laid in successively steppedand partially over: lapping;' relation and forming a series ofc'o rm posite tab sections each of three-ply thickness at its lower edge portion and the remaining'portions of eachtab section being made up of successively fewer plies corresponding substantially to an upwardly tapered. shingle.

In witness whereof we hereunto affix our signatures.
